1-[(Trimethylsilyl)ethynyl]-4-(trifluoromethyl)benzene 40230-95-3 [4-(Trifluoromethyl)phenyl](trimethylsilyl)acetylene CAS 40230-95-3

Description

Structurally, 1-[(Trimethylsilyl)ethynyl]-4-(trifluoromethyl)benzene 40230-95-3 [4-(Trifluoromethyl)phenyl](trimethylsilyl)acetylene (C12H19F3Si) contains fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 248.36 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

1-[(Trimethylsilyl)ethynyl]-4-(trifluoromethyl)benzene 40230-95-3 [4-(Trifluoromethyl)phenyl](trimethylsilyl)acetylene (CAS 40230-95-3), molecular formula C12H19F3Si and molecular weight 248.36 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
